R600 Gallium3D Shader Compiler Milestone Hit

Phoronix: R600 Gallium3D Shader Compiler Milestone Hit

Beyond working on a R600/700 winsys as well as a command submission checker for these ATI Radeon HD 2000/3000/4000 series graphics processors, Jerome Glisse of Red Hat has also been busy at work on a shader compiler for the R600/700 ASICs with the still-in-early-development Gallium3D driver. Over the weekend Jerome hit one of his first milestones with this code. As Jerome mentions on his blog, the shader compiler is still beginning to work: as in a tri-flat being rendered using this new compiler infrastructure...

Nice! My last video card was an r300 and I think the work on that has been pretty much exhausted. I have an r700 now and glad to see someone working on my card. Hope performance gets up to or even exceeds Windows performance (exceed perhaps by being more flexible and configurable).

How long until I can run Doom 3, Nexuiz, Google Earth, X3, Jack Keane, & the Penumbra series etc. with open source drivers on an r600+ at max settings? Ever?

Doom 3, Nexuiz, and Penumbra work already on the classic Mesa driver in Mesa 7.8.

I haven't tested the other ones, but I suspsect they'll work.

However last I checked the shadows are messed up in Doom 3, so I had to disable them. And the performance isn't that great. I'd say Doom 3 and Prey were getting about 20-30fps on Medium/High. I didn't benchmark them; but they were playable.
